Department of Buildings denies de Blasio request — twice

Not even the mayor of New York City is immune to Department of Buildings bureaucracy.

Mayor Bill de Blasio has applied for a DOB document twice over the past five months that would verify that he and his wife are legally using the Park Slope row house they own but rent out. Both times, the DOB gave the de Blasios’ application the thumbs down, citing a lack of proper paperwork.

The duo are after a letter of no objection for their 384 11th Street property, which serves as a certificate of occupancy substitute for homes built prior to 1938, DNAinfo reported. Prior to that year, certificates of occupancy weren’t issued for residential properties.

“The department is working with the applicant and expects the request to be resubmitted along with the necessary documents,” Kelly Magee, a spokesperson for the DOB, told the news site.

The de Blasios pursuit of the document is also intriguing, as an LNO is only necessary for residential property owners if they are either selling their home or refinancing and looking to officially confirm its legal use to a third party. But a spokesperson for the Mayor’s Office denied that the de Blasios were looking to sell, though she also declined to give a reason for seeking the LNO.
